Jet Grouting is a technique of mixing in-situ soil with the energy of high-pressure jet of slurry. A small-diameter rod drills down to the improvement bottom. Then the rod, while being withdrawn, jets the cement-base slurry and air to produce an improved column. The compressed air and hardening agents which usually consists of cement and water are jetted with a high-pressure …

mounted jet grouting nozzle. Step 2: A jetting fluid (water and/or binder suspension depending on the type of jet grouting process) is pumped through the jet grouting nozzle at high pressure (400 - 600 bar). This produces a high-energy "cutting jet" which erodes the soil from its natural position and mixes it with the binder suspension.
